PRINTING ATTAGI-HWENT FOR, PAPER-ROLL HOLDERS.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed April 9. 1907. Serial No. 367-173.

To all whom it may concern:

Be it known that I, JOHN LEWIS LAM- BOLEY, a citizen of the United States, residing at Fort Vayne, in the county of Allen and State of Indiana, have invented a new and useful Printing Attachment for Paper- Roll Holders, of which the following is a specification.

This invention relates to printing means to be employed in connection with rolls of wrapping paper for the purpose of printing advertisements, announcements, and the like on such paper when it is drawn from the roll.

The primary object of the present invention is to provide novel, simple and effective means of this character that can be readily attached-to a roll holder, will print the desired matter clearly upon the paper, and will blot or dry the ink immediately after printing in order to avoid the smearing of the printed matter when the paper is wrapped upon a bundle or package.

The preferred embodiment of the invention is disclosed in the accompanying drawings, wherein Figure 1 is a perspective view of a paper roll holder and paper roll therein showing the improved attachment applied thereto. Fig. 2 is a vertical sectional view on the enlarged scale through the mechanism. Fig. 3 is a view in elevation of the under side of the attachment. Fig. 4 is a detail perspective view of the clamping means.

Similar'reference numerals designate corresponding parts in all the figures of the drawings.

The roll-holder, designated as a whole by the reference numeral 5, may be of any well known character, and in the embodiment illustrated, includes a top cross bar 6, to

which the attachment is secured.

The usual roll of paper is shown at 7.

The printing mechanism comprises a casing 8 having its under side open, and rotatably mounted therein is a printing member comprising end walls 9 mounted on a shaft 10 and journaled in the end walls of the casing. Connecting the end walls are a series of channel bars 1 1 constituting holders for rubber or other suitable type 12. Inasmuch as a series of these holders are employed, it will be evident that practically any advertisement or announcement may be set up as de-- sired. A permanent announcement or advertisement as 13, may also form a art of Arranged Wit 'n the casing at one side of the member are spaced swinging arms 14:, and j ournaled thereon, are inking rollers 15 that are in contact, one of the inking rollers operating against the printingl face as the printing member rotates, the ot er constituting a distributer. Springs 16, bearing against the arms, serve to hold the rollers in operative relation to the printing member.

The casing 8 is carried by swinging arms 17 pivotally mounted in the ends of a bar 18, constituting a part of the meansfor securing the device to the roll holder. Spring arms 19, secured to the bar, bear against the arm 17, and serve to urge the casing downwardly and inwardly. The clamping means consists of a pair of hooks 20 arranged. to embrace the cross bar 6 of the roll holder, said hooks having arms 21 that are angularly disposed and slidably passed through the bar 18. Set screws 22 serve to hold these arms against movement and in adjusted position. It will thus be evident that if the parts are clamped to the roll holder as shown in Figs. 1 and 2, the casing with its printing member will be urged by the spring arms 19 towards the roll 7.

The following means is preferably employed-for effecting the rotation of the printing member. Roller engaging wheels 23 are journaled on the opposite end walls of the casing and rest against the face of the paper roll, said wheels preferably having roughened peripheries. One of the wheels has a shaft 24 projecting into the casing and having a pinion 25 thereon. This pinion meshes with another inion' 26 that is in turn in mesh with a gear w eel 27 fixed to the adjacent end of the printing mechanism. The wheels 23 have the portions which engage the paper roll disposed nearer the shaft 10 or axis of rotation of the printing member than the printing face of said member. Consequently it will be evident that while the printing member is located within the casing, the wheels 23 will bear against the paper roll but when said printing member has been revolved through the medium of the intermeshing gears so that the printing face comes into contact with the face of the paper roll, then the casing will be raised so as to carry the wheels 23 away from the paper roll and the printing face will be held in contact with the face of the paper by the additional tension thus imparted by the springs 19. Directly in rear of the wheels 23 and the printing member is a roller 28 having a blotter 29 on its outer face, said roller being carried by spring arms 30 that serve to maintain it against the face of the paper.

The operation of the device is substantially as follows. As the roll of paper 7 is rotated by pulling the free end of the paper therefrom, it will be evident that the wheels 23, because of their frictional contact with such roll, will be rotated, and therefore the printing member will be rotated. Consequently if an advertisement, announcement or other display matter is set up or placed upon the printing member, the same will be brought into contact with and printed upon the paper, the blotter 29 absorbing and drying the print so as to avoid its becoming smeared from handling afterwards. It will be evident that this structure is very simple, that any desired announcement or advertisement matter may be displayed, ahd that the same will be printed consecutively, the speed of rotation of the printing member being varied by changing the gearing. The device is readily applicable to any ordinary paper roll holder, inasmuch as it only requires the clam ing of the hooks upon the frame of such he der.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in they art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as'new, and desire to secure by Letters Patent, is
